First, find Bifocal Safety Glasses Walmart your current prescription. I keep mine in medical file in my filing cabinet. If you can’t find your prescription, visit wherever you last longer had your eyes examined and request a backup. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription for you. You now need to make note of a few critical pieces of information from your prescription (see example above–click to enlarge). Among other information, you should see three columns on your prescription–sphere, cylinder, and axis.
Bifocal Safety Glasses Walmart » Within the example above, these are abbreviated SPH. CYL. and AXIS. These three columns will have two rows, Right and Still left. Within the prescription above, this is simply abbreviated R and L. Many doctors instead use the latin abbreviations, which can be OD and OS. OD means right eye and OS means remaining eye. Jot down a quick copy of the six volumes or simply keep the prescription handy. These six critical quantities define how your lens will be carved. Any online eyewear retailer will require the input of these six numbers.
In addition to these six statistics, there is yet another critical amount, the Pupillary Distance, or PD. This is a solution, in millimeters, of the space between your eye. Bifocal Safety Glasses Walmart Within the example prescription above, you will see the Pupillary Distance of the patient is 62. Write down this amount also, it’s the seventh of your seven critical amounts.
A somewhat less critical amount is your temple period. If you’re lucky, you’ll also see a temple length and bridge size in your prescription. If not, don’t sweat it, you can body it out yourself. The temple size describes the distance of both bars that connect the spectacles to your ears. It is measured from where in fact the 90-degree curve from your lens structure aside bars (temples) starts to the end of the temple, including the curve. It isn’t measured from the flex point of the temples, because the “stub” between your flex point and lens structure is not a standard size.

Now, take out some measuring tape (ideally the kind of tape used for fitting clothes and sewing, as it’s very flexible) and measure an existing pair of spectacles that fit comfortably. An average temple span for men is 135mm or 145mm. For women, 130mm to 140mm is standard. When your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the dimension in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eyeglasses stores, temple period is shown within a frame description and is also not customizable. Therefore, you need to find a frame with an appropriate temple size. This sometimes varies if you are at a site focusing on designer spectacles, where you have the option to input your own temple size.
Truthfully, temple size is not a huge deal. I’ve one pair of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably. If for reasons uknown you can’t come up with a temple measurement, don’t let that stop you from making an eyewear purchase online. Instead, simply choose 140mm temples if you are a man and 135mm temples if you are a female. It’s likely that, this size will fit perfectly.
